Cleanup: GPU: Set default GL_UNPACK_ALIGNMENT to 1

Browse Source 
Ogl default is 4 but for almost all cases, blender use tightly
packed format. This avoid confusion and state change for the
common case.

The only case that __might__ need alignement is DDS loader
(untested) so leaving this as it is.
